Abstract: A tyre and wheel rim assembly for a vehicle, the tyre (1) comprising a pair of bead regions each reinforced by a bead core (5) and the wheel rim (2) comprising a pair of bead seats (6,7) characterised by one bead region of the tyre having an additional retention zone (18) positioned axially inwards of and integral with the main bead region, the retention zone (18) having an axially inner tip or toe (21) substantially inwards of the main bead region and the construction of the bead between the bead core (5) and tip (21) providing substantial resistance to compressive forces therebetween, and the wheel rim (2) comprises axially inwards of and adjacent to one of the bead seats (6,7), which is that part of the bead seat contacted by a standard tyre, a circumferentially extending toot (21) having a sharp edge inter-engaging only the retention zone (18) of the tyre at the tip (21) such that when lateral force is applied to the tyre tread and internal inflation pressure is low, axially inward movement of the tip (21) is resisted by tip-to-tooth inter-engagement thus causing bead rotation about the tip (21) and generation of compression force in those parts of the bead region between the tip (21) and the core (5) to provide bead retention at the bead seat. 
     The invention also provides a wheel rim and a tyre having the above features.

Abstract: A system for detecting an overheat condition and fires in the cargo bay of an aircraft comprises a control unit (22,24) attached to the aircraft; and a plurality of thermal imaging modules (31-40) coupled to said control unit (22,24) and positioned in direct view of cargo containers (230-237) in the cargo bay. The thermal imaging modules (32-40) have an infrared detector for sensing an overheat condition on the outside of cargo bay containers indicating a fire within said containers and outputting a signal to the control unit (22,24), the thermal imaging modules (31-40) being sized and positioned in the cargo bay so as to not interfere with the loading and unloading of the bay. Preferably, the system comprises plural control units (22,24) which execute routines to monitor and test their operational status and that of each thermal imaging module (31-40). The control units (22,24) are connected to the aircraft electronics to indicate the location of an overheat condition or any malfunctioning control units and thermal imaging modules. The thermal imaging modules (31-40) include an infrared detector, a rotating optical assembly, threshold circuitry and a motor. The optical assembly is rotated by the motor to give the detector with a conical field of view. The optical assembly focuses the radiation in the cargo bay on the infrared detector. If the infrared detector measures a radiation level equal or greater than that of a fire, the threshold circuitry outputs an overheat signal to the control unit (22,24). The thermal imaging module (31-40) also includes a thermal switch that will trigger an overheat signal if the temperature of the module itself is above a specified temperature.

Abstract: Method of determining free subareas on an area partially covered with rectangular objects and also a method of determining free spaces in a space partially filled with objects in the form of a right parallelepiped, in which method an essentially rectangular area to be covered or a space to be filled is depicted in the form of a two-dimensional or three-dimensional matrix, respectively, each element of the matrix representing a rectangle on the area or a right parallelepiped in the space and it being established for each element whether the corresponding rectangle in the area or the corresponding right parallelepiped in the space is free or occupied, after which the number of rows and columns and, possibly, layers of the matrix is reduced in accordance with a fixed algorithm until the unit matrix has been reached. During the matrix reduction, a search is continuously made for matrix elements which have a first logic value and which are bounded on all sides by elements having a second logic value; such an element indicates the presence of a free space in the (reduced) matrix. A dimension table is also determined for each of the dimensions, the length of each table being linked to the number of rows, columns and, possibly layers, respectively, of the matrix. During the reduction of the matrix, the dimension tables are updated in accordance with a fixed system, with the result that, whenever a free area or a free space is found during the reduction of the matrix, the position of said area or said space can be read off from the table.

Abstract: Disclosed is a system that uses two character positions (706) on a display area (702) of an oscilloscope to indicate the progress being made toward a achieving a target number of waveform acquisitions. The system displays the percentage of waveform acquisitions taken within this two character percentage display area (706) by first displaying two symbols as white dots on a dark background (802). As the percentage of waveform acquisitions taken increases, the dots within the symbols are inverted starting at the bottom of the display area and progressing toward the top. When the target number of waveform acquisitions have been taken, all the dots within the symbols are inverted to display dark on white. As the percentage increases, the dots forming the first character of the display are inverted prior to the dots forming the second character (Fig. 8B). Therefore, higher resolution of the display is obtained.
